A new preparative method for N-adamantylation of carboxylic acid amides, ureas and for C5-adamantylation of barbituric acid in trifluoroacetic acid (TFA) is proposed. Tertiary 1-adamantanols and 1-(1-adamantyl)alkanols were used as adamantylating agents. The reaction of 1-(1-adamantyl)alkanols with nitriles in TFA solution was employed for the first time for the preparation of N-[1-(1-adamantyl)alkyl]amides.

4‐chloroacetoacetic ester were introduced into the domino SN2 → Thorpe‐Ziegler → Guareschi‐Thorpe reaction to synthesize tetracyclic dipyridothiophenes. Starting from these compounds, 8,9‐polymethylenepyranothienodipyridines were also synthesized by the domino Knoevenagel → Michael → hetero‐Thorpe‐Ziegler reaction. Furthermore, a method for the synthesis of thienodipyridine annulated to the steroid skeleton
